If you've been shopping for jewellery that doesn't tarnish, doesn't peel, and holds up to real daily life — you've probably come across the term PVD gold. But what does it actually mean, and why does it matter?
This guide explains the science behind PVD gold in plain language, so you can make a genuinely informed decision about what you wear against your skin every day.
What Does PVD Stand For?
PVD stands for Physical Vapour Deposition. It's a vacuum coating process used across aerospace, medical devices, cutting tools — and jewellery. In the context of jewellery, it refers to a method of bonding genuine gold onto a base metal at a molecular level.
It is not painting. It is not dipping. It is not electroplating. It is a fundamentally different process that produces a fundamentally different result.
How PVD Gold Works
Here's the process, simplified:
- The base metal piece (in Carryallco's case, 316L surgical-grade stainless steel) is placed inside a vacuum chamber.
- Gold is vaporised at extremely high temperatures inside the chamber.
- The vaporised gold atoms travel through the vacuum and deposit directly onto the surface of the stainless steel.
- The atoms bond at a molecular level — not just sitting on top, but becoming part of the surface.
The result is a gold layer that is genuinely fused to the base metal, not merely stuck to it.
How Thick Is PVD Gold vs Standard Gold Plating?
This is where PVD gold separates itself clearly from standard gold plating:
- Standard electroplated gold: typically 0.5–1 micron thick
- PVD gold: typically 2–5 microns thick — 3 to 5 times thicker
Thickness matters because a thicker layer means more gold between your skin and the base metal, more resistance to wear, and significantly longer lifespan before any degradation occurs.
Why PVD Gold Doesn't Peel or Chip
Standard gold plating is applied via electroplating — an electrical current deposits gold ions onto the surface. This creates adhesion, but the bond is relatively weak and sits on top of the surface rather than integrating with it.
PVD gold bonds at the atomic level. The gold atoms physically embed into the surface structure of the stainless steel during the deposition process. There's no layer boundary in the traditional sense — the transition from steel to gold is gradual at the molecular level. This is why PVD gold doesn't peel. There's nothing to delaminate from.
Why PVD Gold Is Waterproof and Sweat-Resistant
Two factors make waterproof jewellery possible with PVD:
- The base metal: 316L surgical stainless steel is completely corrosion-resistant. It doesn't rust, oxidise, or react with water or sweat.
- The PVD gold layer: Gold itself is chemically inert — it doesn't react with water, oxygen, or the acids in your sweat. And because the PVD bond is molecular, water can't penetrate beneath the surface to reach the base metal.
Standard gold-plated jewellery fails in water because moisture seeps through micro-cracks in the thin plating and oxidises the copper or brass underneath. With PVD on stainless steel, neither layer is vulnerable to water.
The 316L Stainless Steel Foundation
PVD gold is only as good as what it's bonded to. Carryallco uses 316L surgical-grade stainless steel — the same specification used in surgical instruments, medical implants, and body piercings. It is completely corrosion-resistant, nickel-free, and hypoallergenic.
Is PVD Gold Real Gold?
Yes. The gold deposited via PVD is genuine 18-karat gold — 75% pure gold by composition. It is real gold, applied using a more advanced method than traditional plating.
How Long Does PVD Gold Last?
With normal daily wear, 18K gold PVD jewellery typically lasts 5 years or more before showing any significant wear. This compares to standard gold plating at 2–6 months, and gold vermeil at 6–18 months.
Carryallco backs this with a 5-year anti-tarnish warranty. If your piece tarnishes or the plating fades within five years of normal wear, we re-plate it. No questions asked.
Who Should Buy PVD Gold Jewellery?
PVD gold is ideal if you want gold jewellery for daily wear, live an active lifestyle, have sensitive skin, or deal with India's heat and humidity every day.
